Sustainable development

Sustainable Development

Sustainable development is a holistic concept that combines the need to protect the environment with the demand for socio-economic progress. It ensures that development meets the needs of the present without compromising the ability of future generations to meet their own.

Key Concepts

• Sustainable Development Goals (SDGs): A series of 17 international development goals from the United Nations to be achieve by 2030. They cover areas such as poverty reduction, health improvement and climate action.

• Sustainability: The capacity for an ecosystem, settlement or economic model to remain diverse and productive over time. It encompasses three main pillars: economic, social, and environmental.

• Carrying Capacity: The theoretical maximum population that an area or planet can sustain indefinitely. Exceeding this can lead to environmental degradation and resource depletion.

• Ecological Footprint: A measure of the human impact on Earth’s ecosystems. It reflects the amount of biologically productive land and sea area needed to supply the resources a human population consumes and to assimilate associated waste.

Understanding Sustainable Development

• It requires long-term thinking, considering not only immediate needs and desired outcomes, but also the potential for unforeseen, future impacts.

• Sustainable development calls for a balance between socio-economic development and environmental protection. This does not always mean compromise or sacrifice in the short-term; often, sustainable practices result in long-term economic savings or benefits.

• An understanding of the interconnectedness of systems – social, economic, environmental – is at the heart of sustainable development. Decisions in one area always have repercussions in others.

• Policies and approaches should be flexible and adaptable, able to modify based on changing circumstances or new information.

Importance of Sustainable Development

• Preventing Environmental Degradation: Avoids the depletion of resources, maintains biodiversity, and helps to control hazards like climate change or pollution.

• Supporting Economic Sustainability: Encourages the sustainable use of resources, calls for socially equitable distribution of wealth, and promotes long-term economic stability over short-term gains.

• Promoting Social Equity and Peace: Strives for fairness, social cohesion, and inclusivity. It recognises that sustainable development can only be achieved if all members of society are included and considered.

Challenges for Sustainable Development

• Population Growth and Urbanisation: The world’s population continues to grow and urbanise, leading to increased demand for resources and intensified environmental threats.

• Contradictory Objectives: There may be competition between the three pillars of sustainability (economic, social, environmental), leading to tough choices.

• Political Will and Public Support: Achieving sustainable development often requires collective actions, policy changes, and potentially challenging the status quo – which may be politically or publicly unpopular.

• Inequality and Poverty: Sustainable development must face the challenges of addressing inequality and poverty, which are often systemic and deeply entrenched social issues.
